Description: Main Erase Lamp LA1 Lamp’s failure to turn ON, lamp out, lamp terminal/connector left disconnected
No current flows for 1 sec. or more after LA1 has been turned ON.
Remedy: Check 1. Is power (DC24V) being supplied from PWB-A to LA1? • Once the Power Switch has been turned ON, there should be DC24V across pin 4 of PJ7A on PWB-A and GND. Check 2. Is an LA1 Remote signal being output from PWB-A to LA1? • When LA1 is turned ON, there should be approx. DC1.2V across pin 5 of PJ7A on PWB-A and GND.
Code: C0F30
Description: ATDC Sensor T/C ratio too low
T/C ratio becomes 1.4% or less.
Remedy: Check 1. Is the ATDC output voltage being output from the ATDC to PWB-A? • The ATDC output voltage is detected across pin 13 of PJ8A on PWB-A and GND. DC3.5V when T/C is approx. 1.4% DC2.5V when T/C is approx. 4.0% Check 2. Is power (DC5V/DC24V) being supplied from PWB-A to PWB-E? • Once the Power Switch has been turned ON, there should be DC24V across pin 16 of PJ8A on PWB-A and GND. • Once the Power Switch has been turned ON, there should be DC5V across pin 17 of PJ8A on PWB-A and GND.
